    7984    of <quote>eth0</quote> in the network interface configuration files
    8085    below.</para>
     86
     87    <para>Note that the rules above don't work for every setup. For example,
     88    MAC-based rules break when bridges or VLANs are used, because bridges and
     89    VLANs have the same MAC address as the network card. One wants to rename
     90    only the network card interface, not the bridge or VLAN interface, but the
     91    example rule matches both. If you use such virtual interfaces, you have two
     92    potential solutions. One is to add the DRIVER=="?*" key after
     93    SUBSYSTEM=="net" in MAC-based rules which will stop matching the virtual
     94    interfaces.  This is known to fail with some older Ethernet cards because
     95    they don't have the DRIVER variable in the uevent and thus the rule does
     96    not match with such cards. Another solution is to switch to rules that use
     97    the bus position as a key.</para>
     98
     99    <para>The second known non-working case is with wireless cards using the
     100    MadWifi or HostAP drivers, because they create at least two interfaces with
     101    the same MAC address and bus position. For example, the Madwifi driver
     102    creates both an athX and a wifiX interface where X is a digit.  To
     103    differentiate these interfaces, add an appropriate KERNEL parameter such as
     104    KERNEL=="ath*" after SUBSYSTEM=="net".</para>
     105
     106    <para>There may be other cases where the rules above don't work. Currently,
     107    bugs on this topic are still being reported to Linux distributions, and no
     108    solution that covers every case is available.</para>
